Also I would like to stress out that you (in general) should not use
the portable branch on OpenBSD. It is not supposed to work and if it
does, it still is not supposed to ;-)
For the archives:
The OpenBSD master and portable branches have very very slight diffs
and we try to keep them as minimal as possible. However, OpenBSD has
some features we want to use and that do not always exist elsewhere.
Sometimes the feature is simple enough that we can add a function to
the compat glue and use it if not present on the system. This is the
case for strl*(3), closefrom(2) and more ...
Sometimes the feature is trickier and is not something you can write
as it requires help from the kernel. In such cases, we can either do
a work-around that closely but imperfectly mimics the original stuff
or we simply don't provide the feature. This happens in many places,
for example interface groups which work on OpenBSD but not on others
or getdtablecount(2) which exists on OpenBSD but is emulated using a
trick that's not too bad but not too good either.
With this in mind...
The master branch is *heavily* tested on OpenBSD.
The portable branch is *heavily* tested on Linux/FreeBSD.
The portable branch is *never* tested on OpenBSD.
When you run portable branch on OpenBSD, we don't know how the
work-arounds behave and if they work as good as on other systems.
We don't even know which ones kick in and I would have to go check
each one individually just to be sure if I was asked.
In theory, it should work, in practice it's not tested and the
executables generated from building master / portable are different
so you're essentially running a subtly different code that's
untested.
Voila !
